Application filed Julyl2, 1917. Serial No. 172)203.

ToaZZ whom t may concern:

Be it known that I, CHARLES B. DRAKE, citizen of the United States, residing at Norfolk, in the county lof Norfolk and State of Virginia, have invented certain new and useful Improvements in Vulcania-ers, of which the following is a specification, reference being had therein to the accompanying drawing.

rlhis invention relates to portable vulcanizers adapted to be carried on the person or in the usual tool kit or boX of motor vehicles, and to be used primarily in applying patches to inner tubes.

The invention has for its object the provision of a simple, inexpensive, and practical device of the character stated.

A convenient and the preferred embodiment of the invention comprises a vulcanizer implement, the component parts of which in one position constitute a clamping and heating means for the tube and applied patch, andV in another position constitute a container for patches and the like; a part of the clamping means being utilized to also serve as fastening means to secure the container in closed position; the clamping instrumentalities for the tube and patch being constructed to have a universal movement or play to the end that the clamping faces may assume parallelism while the^ rubber is being vulcanized; and one of the clamping faces" being so associated with this carrying part of the-container that it may' be odset into a projecting position from the adjacent surface of said part, when performing its clamping and vulcanizing function, and may be restored to a common plane, that is a plane coincident with the adjacent surfaces of the clamping member and the part carrying the same to avoid the offsetting or projecting of the clamping part when the container is in closed condition.

All of the foregoing desirable character-` istics of the particular embodiment of the invention to which I have alluded will be better understood, and the improved details in construction and arrangement of' parts will also be made clear* from.` the speciic description hereinafter contained when read in connection withI the accompanyingV drawings, wherein the said pre1 ferred embodiment of the invention. is illustrated.

In the drawings: j j

Figure l is a perspective view of the device in its closed or container position;

Fig. 2 is a perspective view of the device in clamping or vulcanizing position;

Figs. 3 and l are longitudinal sectional views of Figs. 1 and 2;

Figs. 5 and 6 are transverse sectional views ofthe same gures; and,

Fig. 7 is an end view of Fig. 1.

Referring more specifically to the drawings, wherein like reference letters designate corresponding parts of the several views, A represents the bottom member having a flange B extending around the sides and front end but open at the back as at D, and C represents a top member having side flanges E and an open end F.

A hinged plate G is hinged along one edge as at H to the back edge of the bottom member A, and this hinged plate,-or what may be termed the rear end closure,- is also indirectly hinged `as at I to thetop` of the upper member C through the medium of a member J pivoted centrally as at K to the `hinged plate to permit transverse rocking movement of the member C` on the hinged plate, when opened for a purpose as will later appear, the adjacentl edges of' the hinged plate being cut away or rounded as at L to permit this rocking movement.

rPhe forwardl end ofV they member C is curved as at M to correspond with the curvature of the closed forward portion of the flange on kthe bottom member A and thereby, together', to form a circular opening N in which a clamping and vulcanizing member C is centrally located and pivoted `at opposite points by headed pins P to the arms Q of the member C bordering its cutaway or curved end. The clamping member" is in the nature of a cup capable of having its position reversed and the same is mounted for the pivotal movement on the pins referred to by means of ears R in which are` kop'positely disposed bayonet shaped slots S' receiving the Shanks Vof said headed pins, the short ends of said slots projecting in the same direction circumferentially of the' circular clamping member so that by the rotary movement of the latter, the pins will be engaged with the horizontal shoulders to hold the clamping member in the projected position shown in Fig. 2, or with the vertical portions of the slots to permit theV clamping member to be forced inwardly to haverits face in approximately the plane of the face of the uppermember C when the device is not in use, it being here understood that when the clamping member is in vulcanizing position it should be oset from or projected away from the face of the member C to coact properly with Vthe opposing bottom (then the upper) face of the lower member C, when the members A and C are reversed back to back as is ofcourse readily understood from the drawings. The transverse rocking movement of the clamping member O on the pivot pins enables the clamping face of said member to adjust itself notwithstanding the angula-rity of the members A and C when the device is opened with the members A and C reversed, as stated, and the pivot at the back of the members C which carries the clamping member and permits said member @,and incidentally the clampingmembcrO, to rock transversely, coperates to give the clamping member O a universal play to all extent that is necessary to bring the clamping faces into parallel relation.

Adapted to fit the interior Vof `the cupshaped clamping member is a heater T, itself in the nature of a flanged cup adapted to fit the cupslike clamping member, and formed of metal with the integral spiral rib coiled about the interior thereof, the p urpose of this device being to contain the little liquid adapted to be burnt and to generate adequate heat to be transmitted through the clamping member O tothe rubber tube and patch inclosed between the clamping faces when the patch is to be vulcanized to the tube, which operation will be readily understood.

The upper member C is provided with a Vsmooth apertured portion V, while the bottom member is provided with an approximately alined apertured portion W, said apertured portion being adapted to receive a thumb screw X to clamp the container either in its closed condition as shown in Fig. 1, or in its clamping position with the container members reversed as shown in Fig. 2.

The interior ofthe container is of a size to carry a number of patches, as represented at,Y,`or a number of vcombustible disks represented at Z and composed of any suitable material, known in the art, for creating the necessary heat to insure vulcanization, the

disks being adapted to be employed when the liquid burner previously alluded to is not to be used.

When the container is partially empty, so

that there is room therefor, the clamping part O may be swung around into a reversed position on its pivots so that the clamping face may be forced into the interior of the container and thereby preserve .such face against damage. This is indicated in full lines in Fig. 5, the other inclosing position of the clamping part O being shown in full lines in Fig. 1 when the container is initially filled with supplies.

It is believed unnecessary to further outline the operation of the device inasmuch as this will be clear from the foregoing description of the structure and purposes thereof.

lllhile I have herein disclosed a special embodiment of the invention it will be understood by persons skilled in the art to which the invention relates that the same is capable of embodiment in still other forms and devices without departing from the spirit of the invention.

Having thus described the invention, what l cla-im is:

1. .i combined container and vulcanizingdevice comprising oppositely disposed members connected to occupy a closed position or a reversed clamping position and a common means for Securing` the members in closed or clamping position.
